<p>The "dancing" robots certainly are compelling to view, though I
can see why Gary asked if it was real or memorex (CGI)... there
was enough uncanny valley going on in their moves to make it clear
that they were following a prescribed choreography. The
miniscule detail in the dance moves is what I *think* makes it
impressive. I am doubting that the proportions and range of
motion/etc of the robotic humanoids is as close to humans' as
implied by the constraints (in software, in choreography)
imposed. <br>
</p>
<p>I also wonder how much of this is essentially driven by something
like MoCap that is then tweaked to match the dynamical performance
envelope/constraints of the robot simulacrum? Or by derivation,
ws ther some kind of machine learning going on on a *suite* of
human MoCap data sets. Or is there a very capable
cyber-choreographer who implicitly understands the robot's
"coupled impedance elements" in a way that allows them to
hack/hint/nuance the instructions down to this level of
performance?</p>
<p>Are these class of robots targeted for mission-spec autonomy or
are they more targeted to default to being Waldos with some
self-driving constraints?<br>
</p>
<p>I haven't tracked whether the Laban Notation movement has
actually been useful to extend into robotic-motion... it starts
to seem relevant once humanoid Robots are presented dancing
human-dances.<br>

<p>The "impressive illusion" is that these Robots are responding to
the music itself and to one another (couples dancing) in a way
that seems highly doubtful. They appear to be merely very artful
puppets with wireless "strings". No small feat, bringing them
to this point, but the most interesting/impressive aspects are
likely careful bit-chiseling on the instruction sets.</p>

It would be more impressive if they were helping an elderly person
go to the bathroom. Chasing a person in irregular terrain would
be convincing too.<br>
